We are seeing more & more bike friendly attitude come recently, with the formation of more mixed used - commercial / residential use , there are a lot more people using bikes as a mode of transportation.We need both parking & bike lanes .

Los Angreles is a huge business center not a recreational area. There are very "chilled" kinda like "yoga" style beachy areas where bike lanes would be perfect, like Venice, Marina Del Ray and Naples. Centinela Ave is a big street that a lot of LA drivers use to get to 405 Hwy. I personally don't think it would be a great idea to convert one of the lane into bike lane. More traffic!

I think we have to make room for alternative modes of transportation in a way that provides stress free travel for all.
The Metro needs to be expanded so that it's a viable option for travel as it is in other major cities.
Bike lanes are great, but not when they compete with car traffic. Some bike lanes are downright dangerous not to mention, clogged with exhaust from the cars.
In my opinion, bike lanes should be set up in a way that protects the bikers, such as the bike route that goes along the Los Angeles River...No Cars! Perhaps an expansion of the beach bike paths all the way to Ventura :). and a protected no car bike lane where the Red Cars used to travel from downtown to the beach. Now that would be nice!

Bike lanes are necessary at the same time neighborhoods such as Miracle Mile can't afford to give up car lanes for bikes because of the heavy concentration of businesses and housing. It is important not overbuild in areas that can't sustain such growth.
